And this is no different than if snapshot was on any other device such 
as esata-hdd, usb-hdd or usb stick.  LVM should handle this.  If the 
snapshot device goes away, then just vgreduce it on the reboot.
Trying to retrofit snapshot into existing systems is far easier if you 
can use ramdisk, esata-hdd, usb-hdd, usb-stick because most systems have 
allocated all space and rather than struggling through trying to compact 
and reduce VG, LV, PV, partition, filesystem to gain space it is much 
easier to use other devices.  And again this is something that LVM 
should be able to handle.

part of another volume placed where?  on the snapshot?  I don't 
understand this part.
